Abstract

See full text

A muffler draining apparatus for a working machine is provided which allows a drain line having excellent heat resistance to be reliably installed, even when a device or equipment is present at the position below a muffler. In a muffler draining apparatus that is provided to a muffler equipped to a hydraulic excavator, and includes a drain line that discharges water accumulated in the muffler to the outside of a vehicle body, the above-described drain line includes a single metal tubing whose one end is connected to the muffler, and whose intermediate portion provided continuous to the one end is extended into the space formed between the muffler and a hydraulic pump located below the muffler. The intermediate portion of the metal tubing includes a single linear portion and plural bent portions. Also, the muffler draining apparatus includes, for example, a single support bracket that is fixed to the muffler, and supports the intermediate portion of the metal tubing.
